Except in white water rapids. Where you're supposed to put your feet first, and keep your head above water, aided by your life vest. Except the water in the rapids is lighter because of the air mixed in, so your head doesn't stay above water all the time because your buoyancy changes. And if you don't know how to hold your breath right, because you can't do the crawl-type strokes and never learned the whole breathing thing, you take in water in your nose during the rapids. And then you panic.

Fortunately, you are among friends who help fish you out of the river before you panic further, or drown. But then you see the scene in Ratatouille where the rat goes through the "rapids" in the Paris sewers and it's like you're drowing all over again.

Hi! ;-) I'm not still upset about that at all. ;-)
